IMPROVEMENT IN SEAL-LOCKS.

Specification forming part of Letters Patent No. 201,076, dated March 5,1878; application filed December 26, 1877.

To all whom it may concern:

Be it known that I, ANDREW F. WRITING, of Norwich, in the county of NewLondon and State of Connecticut, have invented certain new and usefulImprovements in Seal-Locks; and I do hereby declare that the followingis a full, clear, and exact description of the invention, which willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and toletters of reference marked thereon, which form a part of thisspecification, and in which- Figure 1 is a side view of my improvedseal-lock. Fig. 2 is an end view of the same. Fig. 3 is a section of thehasp-post on the line as w of Fig. 1. Fig. 4 is a detached perspectiveview of the hasp seal locking device. Fig. 5 is a section of the postwhich receives the free end of the lever and seal, on the line 2 'z ofFig. l; and Fig. 6 is a key adapted to set the seal-locking device.

Corresponding parts in the several figures are denoted by like letters.

This invention relates to certain improvements in seal-locks.

It consists, first, of a hasp fitting over a post adapted for theattachment thereto of a seal; secondly, of a hasp fitting over a postadapted as aforesaid, and having a lever; thirdly, of a hasp fittingover a post adapted as before mentioned, and having a lever resting in asecond post having a seal; and in the special construction of the mainfeatures, substantially as hereinafter more particularly set forth.

In the annexed drawing, A refers to a hasp connected to the door, andfitting over a post,

B, in practice secured to a car or other structure. C is a lever pivotedbetween said post and a stud, b, and at right angles to said post. Whenthe hasp is in position upon the post B, the lever C is secured over it,as seen in Figs. 1 and 2, by the attachment to the post B of a seal, D,thus locking the hasp thereon. In the post B is inserted theannnlarlygrooved seal-locking device E, its ends being provided withslots 6 e, to mesh with slots f f in the post B, to permit of theattachment of the seal D to the post. In the post B isalso aspringcatch, g, which engages with notch h in the annularly-grooved orreduced portion of the device E, as shown in Figs. 3 and 4, to hold thesaid device in a locked position. By turnin g the device E with the keyE, upon the insertion of the seal, a half-revolution toward the beveledportion i thereof, it will be brought around so as to cause its stop '6to strike against the catch g, and thus lock the seal in place. The freeend of the lever C rests in a slot in a second post, F, within which itmay be locked by a second seal, G, having the initial letters of anotherrailroad company.

In the post F is a spring-catch, j, projecting into an inclined ordiagonal slot, k, the object of which is to provide a space above thecatch to permit of the passage of the shank of the seal over said catch,the said shank being cast with the seal at an obtuse angle, in order tofit in the slot k and allow the seal itself to stand at right angles tothe post F.

The seal G is provided upon its inner side with a shoulder or flange, Z,to entirely close the entrance to the slot 70. The shanks of the sealsare bifurcated or left open, as shown at m, Fig. 6, to permit of theirfalling out of the slots of the posts B F when the seal or seals arebroken.

It will be seen that the hasp can be locked in place by either the sealD or the seal and lever C, or by the lever and seal G.

- Having thus described my invention, what I claim, and desire to secureby Letters Patout, is-- 1. A hasp fitting over a post, in combinationwith a lever which is swung into alignment with said post, to which itis pivoted, to permit of the detachment of the hasp therefrom,substantially as and for the purpose set forth.

2. In a seal-lock, the combination, with the hasp A, of the post B,having a seal and mechanism for locking said seal thereto, substantiallyas and for the purpose set forth.

3. The hasp A, in combination, with the seal D, slotted post B, havingthe slotted looking device E, and a spring-catch engaging the saiddevice, substantially as and for the purpose set forth.

4. The hasp A, in combination with the lever 0, post B, inclosing aseal-locking mechanism, and seal D, substantially as and for the purposeset forth.

5. The combination of the hasp A, lever 0, seal D, and slotted post B,having the seallocking mechanism E g, substantially as and for thepurpose set forth.

6. The lever 0, post 13, hasp A, and post F, having the seal G, incombination, substantially as and for the purpose set forth.

7. The combination of the hasp A, post B, having a seal, D, lever G, andpost F, having a seal, G, substantially as and for the purpose setforth.

8. The combination of the seal D with the slotted hasp-post B, havingthe annularlygrooved locking device E, provided with slots 6, notch h,and stop i, and spring-catch 9, substantially as and for the purpose setforth.

9. The lever-post F, having the inclined or diagonal slot 70 andspring-catch j, in combination with the seal Gr, having an obtuse-angledshank, substantially as and for the purpose set forth.

10. A lock-seal provided with a bifurcated or open shank, m,substantially as and for the purpose set fort 11. The seal Gr, having ashoulder or flange, l, at a point between it and its shank, and crossingthe same transversely at its base, substantially as and for the purposeset forth.

In testimony that I claim the foregoing as my own I hereunto affix mysignature in presence of two Witnesses.

ANDREW F. WHITING.
